WebFeb 19, 2013 · Mostly no, because GPU programming languages use different programming model (SIMT). However, AMD GPU do have an extension to OpenCL which provides … WebRDNA runs shader threads in groups of 32 known as wave32. Unused threads in a wave get masked out when running the shader. Make the workgroup size a multiple of 64 to obtain best performance across all GPU generations. To help maximize bandwidth in compute shaders, write to images in coalesced 256-byte blocks per wave.

WebSep 2, 2024 · This sample visualizes how wave intrinsics work. Wave intrinsics are a new set of intrinsics for use in HLSL shader model 6. They enable operations across lanes … WebFeb 24, 2024 · Stream compaction can be scalarized with wave intrinsics so that 64x less amount of atomic operations are performed. The idea here is that we will have a per-wavefront bitmask containing set bits for all lanes that wanted to append. This is retrieved by WaveActiveBallot (IsLightCulledInCurrentThread ()).
WebDec 8, 2024 · For per-primitive culling, use subgroup intrinsics to compact the output triangle indices. While it is possible to create degenerate triangles instead, we recommend using compaction of indices for NVIDIA … WebJul 29, 2016 · Kepler GPUs introduced “shuffle” intrinsics, which allow threads of a warp to directly read each other's registers avoiding memory …
WebMay 24, 2024 · The Intel GPA Graphics Frame Analyzer is a powerful, intuitive, single frame and multiframe (DirectX 11, DirectX 12, and Vulkan) analysis and optimization tool for major graphic API workloads. It provides deep frame performance analysis down to the draw call level, including shaders, render states, pixel history, and textures. WebDec 25, 2024 · Fast forward a few years, wave intrinsics are now available in newer shader models. Wave instrinsics are special shader instructions that allow us to retrieve data from the other threads in a wave, without the need for any synchronisation or expensive trips through memory.
WebSep 5, 2024 · To achieve above GPU-driven rendering functionalities, one will need GPGPU primitives (parallel scan, reduce, histogram, etc) as building blocks, which require proper supports for compute shaders ( subgroup/wave intrinsics, atomics, lds/tgsm, etc).
